Explanation:
package testscores;
import java.util.ArrayList;
import java.util.List;
public class TestScores {
public List<Integer> scorearray=new ArrayList<>();
public TestScores(List<Integer> scores) throws InvalidTestScore{
this.scorearray=scores;
for(int i=0;i<scorearray.size();i++){
if(scorearray.get(i)>100 || scorearray.get(i)<0){
throw new InvalidTestScore(this.scorearray.get(i));
}
}
}
public double average(){
int tot=0;
for(int i=0;i<this.scorearray.size();i++){
tot=tot+this.scorearray.get(i);
}
return tot*(1.0)/(this.scorearray.size());
}
class InvalidTestScore extends Exception
{
private double amount;
public InvalidTestScore(int Score)
{
System.out.println("Invalid Score "+Score);
}
}
}
